King post WWII engraving change?

[heinamj]

I recently acquired a 1945-1946 King 2B Silvertone in very good playing condition. I read in a post by the H.N.White Co.LLC that another King 2B they had “was made just as WWII was winding down hence the change in the engraving.” Their 2B has “Liberty” in script and mine doesn’t have it at all. Mine also has a hallmark that just says “Sterling Bell” with no other symbol.

Does anyone know what change in engraving post WWII they are referring to and what does it mean for my horn?
